Our Mission

To provide quality craftsmanship ensuring projects are completed right the first time, on-time, and to our customer’s total satisfaction.

Est. 1983

Mendon, Michigan

Patrick Jergens, founding father of Jergens Piping Corporation, saw a need and took the challenge! With remarkable drive and vision, this pipefitter formed a company that would excel at providing exceptional mechanical contracting services.

Committed to supplying services and products unrivaled in their dependability and quality, and with a work ethic grounded in integrity and service, he forged a company able to meet all challenges of mechanical contracting. In 1994, the Insulation division was added and later the Millwright, Construction Management, Removable Cover, and the Heating & Air divisions were established as well.
